President-elect Rodrigo Duterte eating with his bare hands at a humble "turo-turo" or eatery is a common sight for many residents of Davao City.

Duterte, the two-decade mayor of the southern city, often jumpstarts his day with a hearty breakfast at a carinderia located near his house at the Doña Luisa Village, a middle-class subdivision.

Ermelita Garcia Castanieto, owner of the Thrunks Place eatery, told ABS-CBN News that Duterte has been her "suki" for six years now.

Castanieto said the firebrand mayor's favorite foods include sautéed monggo beans, gizzard and pork adobo, pansit, and "paksiw na isda."

The turo-turo owner added that Duterte would sometimes foot the bill for all her other customers.

Duterte's family earlier vowed to "bring simplicity to Malacañang" if he becomes president.

He will be sworn in as the 16th President of the Philippines on June 30. -- Report from Vina Araneta, ABS-CBN News Southern Mindanao
